T0 LZZ 107110171/ it may concern:

Be it known that I, ROBERT MCA. LLOYD, acitizen of the United States, whose postoffice address is 100 Broadway, in the borough 5 of Manhattan, in the city and State of New York, have invented certain new and useful Improvements in Storage Batteries, of which the following is a full and true description, reference being had to the accompanying lo drawings, showing a preferred embodiment of the improvements.

The object of my invention is to provide a battery box or jar which shall be practically rigid and adapted to withstand the shocks incidental to all conditions of use; andthe improvement consists in the novel features of construction hereinafter described, and pointed out in the claims.

In the accompanying drawings like letters 2o refer to like parts in the several Views.

Figure l is a perspective view of a batterycompartment with several of the new battery boxes or jars therein and with a portion of the compartment broken away to show its construction. Fig. 2 is a longitudinal section of one, of the preferred battery-boxes- Fig. 3 isa perspective view of the metallic crate constituting the body of the batterybox. Fig. a isaperspective view of the same 3o after the wooden parts have been secured thereon.

A indicates a battery-compartment for holding a plurality of my new battery boxes orjars. Itis preferably made of an outer box C, ofiron or steel, cast in one piece or made up of sheet-metal sections and lined orcoated with acid-resisting material or metal. I prefer to employ for this purpose boards coated with or saturated with acid-resisting 4o material-for instance, yellow pine thoroughly painted with asphaltum varnish-the compartment being then preferably lined with sheet-lead.

The batterycompartment made as described is exceedingly strongand light andis adapted to resist the action of acids spilled or leaked from any of the battery boxes or jars B contained within the compartment, and the compartment is further adapted to 5o resist the shocks due to shifting of the boxes or jars.

To further protect the compartment from acids and from electrical leakage, the boxes or jars B rest upon wooden joists E, treated or painted with'acid-resisting material, as 55 asphaltnm varnish. p

The form of battery box or jar which I prefer to employ is shown in detail in Figs.

2, 3, and 4 of the accompanying drawings. Itis composed of a crate-like body or frame `6o (shown in Fig. 3) made up of the upright and angular corner-irons E and of the horizontal ribs or side bars G, secured to the corner-irons by rivets or other suitable devices. 4 In order to make a tight and smooth joint between the corner irons and side bars, whereby the lead coating (added as hereinafter described) is protected from being cut, the side bars are cut away or dovetailed at their ends and the cornerirons are provided 7o with a beveled edge fitting the dovetailed ends of the bars. In the spaces between the bars G are fitted wooden boards II, cut to tightly fit lthe spaces of the crate. The boards may be renderedhvaterproof and acidresisting by treating or painting with suit` able material, such as asphaltum varnish, and thejoints between the boards and the metallic frame may be pointed up or filled with suitable material.

In Fig. 4 is shown the crate with boards fitted between the bars, the whole constituting a compound box having an open. bottom. This com pound box is preferably lined with an acid resisting material J, (see Fig. 2,) such as sheet-lead, with the joints carefully soldered, calked, or riveted to preventleakage of battery solution, and the whole is preferably coated with sheet-lead I or other acid-resisting material, the outer sheet being 9o folded upon the upper and lower edges of the crate to protect the same from contact of the acids.

K indicates a protecting-strip of lead applied to the upper edge of the box.

O indicates horizontal strips or rods of por- 4celain or other insulating material for supporting plate L and spacing the same from the sides of the box.

P indicates metallic shelf-supports secured loo to the walls of the box and sustaining the insulating-strips O.

The box or jar made as described is prefer-- ably provided with or placed upon a support Vor base E, for which purpose wooden boards treated in or painted with acid-resisting material-asphaltum varnish, for instance-may be employed and may be secured to the box by any suitable means, such as screws, locking-joints, hooks, soldered or molded connections, rbc. This provides a base or support which'in addition to being acid-resisting insulates the battery box or jar from the floor upon which it rests or from the compartment in which it is contained.

L indicates a battery-plate adapted to be secured by the hangers M to a supply-conductor, and N indicates one of t-he hard-rubber insulators between adjacent batteryplates. NA battery-box of a construction substantiallylike that describedis exceedingly strong andldurable, is protected against corrosion by acids, is comparatively light in weight, quite inexpensive in construction, and is adapted to withstand all the shocks and jars flue to use in vessels, vehicles, or cars.

ln making up the crate other forms of corner-irons and bars will readily suggest themselves and may be employed and assembled differently than shown.

While I have herein shown and described one embodiment of my invention which I have found to be practical in operation, it is evident that changes in and modications of the yconstruction herein described may be made without departing from the spirit of my invention or sacrificing its advantages, and I reserve the right to make all such alterations ,therein as fairly come within the scope of my claims.

What I claim isl. A storage-battery box or jar, consisting of a metallic frame composed of a plurality of rigid metallic bars secured together in the form of a crate, with a plurality of non-metallic pieces upon each side filling the spaces between the bars and secured therewith to form a practically-continnous box, and a continuous lining of acid-proof protective material within the box or jar.

2. A storage-battery box or jar, consisting of a metallic frame composed of a plurality of rigid metallic bars secured together in the form of a crate, with wooden boards filling the spaces between the bars and secured therewith, to form a practically-continuous box, and a practically-continuous lining of lead within the box or jar.

3. A storage-battery box or jar, consisting of a tubular body comprising 'a traine composed of a plurality of rigid metallic bars secured together in the form of a crate, with wooden boards secured therewith to form a practically-continuous box, and a continuous lining ot acid-proot` protective material within the tubular body, in combination with an applied acid -resisting bottom secured to the body.

4. A storage-battery box or jar, consisting of a crate-likc metallic body, with a plurality of non-metallic pieces upon each side secured therewith t0 form a practically-continuous box, and a continuous lining of acid-resisting protective material within the box or jar.

5. A storage-battery box or jar, consisting of a crate-like metallic body, with wooden boards secured therewith to form a practicallycontinuous tubular body, a continuous lining of acid-resisting protective material therefor, an acid-resisting bottom secured to said body, and an insulated base or support for the box or jar.

In witness whereof I have hereunto signed lmy name this 22d day of November, 1900.
